Make "bin/phd status" report local daemons from the process list, not a mess of local/remote information
The value of bin/phd status as a mixed remote/local command isn't clear, and the current output is a confusing mess (see T11037).
This also continues letting us move away from PID files.
Test Plan: Ran bin/phd status, saw sensible local process status.
